Evaluation of Control Measures

No increase of malaria infections, or the rapid, drastic reduction of cases during an emergency are true signs that control measures for malaria are effective. Current epidemiological data should, therefore. be available to guide the activities of control personnel.

Evaluation of the effectiveness of the level of entomological and vector control should take into account the results of bioassaying the walls of structures to ascertain the extent of insecticide coverage and residual activity. The number of houses sprayed, not sprayed and refusals, must also be recorded, and the current status of susceptibility of vectors to insecticides needs to be evaluated.
